Abstract
Trim balancing of rotating components in the past has increased manufacturing cost. In many past applications, the time and energy required to trim balance rotating components required partial disassembly of an outer case or structure member. The present trim balancing system allows the gas turbine engine to be balanced with the outer case in situ. Access to a rotating component from the exterior of the case is made possible by a compressor air flow path and a pair of holes. The balancing can be accomplished by adding or removing weights or plugs to a band assembled on the rotating component.
